Download and install Chameleon Wizard from here.
Update it to the latest version if prompted.
Click on the Install tab at the top.
Then based on your current setup choose the appropriate install method. I have OS X on a standalone drive and Windows on it's own drive so my install method would be Boot0md. They are pretty self explanatory. Make sure the correct Target partition is selected and then click the install button. Now once you restart you should no longer see the previous boot0 errors.
